Can we see stars explode?
My question is:
Star 1 is 18 light years from Star 2 and 34 light years from Earth. If Star 2 explodes as a supernova, in how many years would the explosion be seen from Earth?
18
34
52
70
Here is the picture I was given:

If we can see it, I would say 34 because light years are how long it takes us to get there.. Do you think that would be right?
